Outlook - right part of the window?

Hi there,first excuse the bad title but i don't know how to call me problem else *g*

I think everybody knows Outlook - if you click on anything there like "calander" it will appears in the right part of the window.

i need something like that. I've got the Outlookbar on my left site, but how can I realize it? I mean can I predefine (VS.net) where my buttons, checkboxes, ect. should appear when the user clicks on something in my left bar?

Or have I to programm it fully by hand in my code? That wouldn't be could, because I would have to test every position by hand *grrr*
